2.25” ReadyLIFT Leveling Kit with 35's installed on my 2021 F-150

[JoeMo]

I installed the ReadyLift 2.0 kit and put Nitto Terra Grapplers (295X65R20) on the stock wheels with no spacers.

No rub here. Ride quality is a LITTLE bouncier, but very minor difference.

Between the two changes, I gained about 3.5-inches of height in the front end, and about an inch and a quarter in the back.

there is a 1-inch rake on the truck still, which I think will be good for hauling a little bit.

Do the lane keeping assist and other driver assistance features still function properly with your level and larger tires? Also was the dealership able to recalibrate your speedo? Looks great! Thanks!

What are the rim sizes and offset?
what manufacturer?

Alright guys...here we go.

Just got my 2021 5.0V8 FX4 F150 a few weeks ago. Since it had a factory 4 inch rake, went with ReadyLift 2.25" level. Still have about 1.75" rake left. Probably should have went with 2.5" level.

Anyhow, went with BFG KO2 35x12.5xr18 and had no rubbing or any problems at all with this fitment. No cutting anywhere on bumper or control arm. No rubbing at full lock either, even went off road a little bit with some slope terrain, no problems!! No issues with Ford Copilot 360 assist 2.0 either. Just need to recalibrate speedometer to accomodate the 35 inches tires (these KO2's are technically 34.5 inch tall).

Love the setup. Best part?? Since these factory wheels are 8.5 inches wide (as opposed to the 7.5 inches wide from previous models), according to BFG website, they fall within spec for 35x12.5r18. That meant that Discount Tire was able to install them. Way to go Ford for listening to customers.

So happy with this while setup and purchase.

Hope this helps everyone out.

Yep they all work fine. I’m not sure if they recalibrated the speedo, but it isn’t off by any noticeable amount.

"Factory 4" rake"?

Did you get a special model? Because I don't think there is anywhere near that much rake on a stock F-150. More like 2"

Just had 35x12.5/20 Toyo AT3’s and a leveling kit installed. Zero rub at full lock. Previously had the same size tire on a 2019 with 2.5” leveling kit and had a little rub at full turn.

Biggest takeaway I see here is 35x12.5s on stock rims. Would that work with a 6 inch lift too? Trying to delay buying new rims and spread the cost out.

Yes, it was 4 inches. I measured them myself. The 4x4's have about a 2.5"-3" inch rake. FX4 have a about a 3.5" inch rake. I think since I have the V8, the front is lower another half inch because of the weight of the engine.

Has anyone measured the before and after MPG after doing a level and 35s? I've got a 2021 F-150 XLT FX4 with the 3.5 ECO and am getting crazy good highway mileage. I know mileage would drop, but wanting to see if anyone measured. thanks

Nice set up. I just put a set of Geolander, 295/70/18 on stock sport wheels. Tires meseare 34.25, off the rim. Mounted @ 40 psi they are 33.5 with a level on top to ground. I was curious how much space between the driver's side uca ball joint and side wall. I measured mine with a set of Allen wrenches. Could only get 3/8" to clear.

Just finished my build. 2” ReadyLift level kit, 285x65R20 Nitto RG, 20x9 Fuel Blitz. Noticed about a 3 mpg dip after I got everything installed. I have a 3.5L EcoBoost

I have the 5.0L V8 and my mileage dropped about 1.5 mpg as soon as I put the 2.25 inch level. Most likely due to change in aerodynamics and more wind resistance under the truck.

As as soon as I added my 35x12.5r18 BFG KO2's my mpg dropped another 1.5 mpg's. In the end it was a total of about 3-3.5 mpg lost.

Has anyone tried adding wheel spacers to the 35x12.5 tires on the level?

Just for a point of reference - I added 275/65r20 Nitto Terra G2's on the stock wheels and no lift/level - my mpg for initial 1021 miles was ~ 22mpg (mixed hwy/city) and after the larger tires (34.1") I am now at ~ 22mpg - so minimal impact (i assume the mpg would have increased as the engine gets used a bit but in any case my net is very little change).
going wider, more aggressive read and lifting the front would likely have bigger impact

What offset are your rims, do you have any rubbing?

+20. No rubbing at all.
